enricobuehler	c21549c136	feat(host/windows,drivers): gamepad driver attach/heartbeat health surfaced in logs ... The gamepad drivers have no IOCTL plane (hidclass gates the stack), so until now the host had ZERO visibility into whether a driver ever bound: a pad could be "created" with no driver installed and nothing was logged. Two health fields are carved from reserved shm space (layout-compatible; pf-driver-proto pins the offsets): driver_proto — stamped by pf-xusb at device add + per serviced XInput IOCTL (movement = the game-visible path) and by pf-dualsense/DS4 from its ~125Hz timer — and driver_heartbeat. Host-side, every pad owns a DriverAttach watcher fed from the existing service() poll: INFO on attach (WARN on proto mismatch), and after 3s of silence ONE diagnosis WARN combining a cached pnputil /enum-drivers store check, the devnode's CM problem code (CM_Locate_DevNodeW/CM_Get_DevNode_Status on the instance id now captured from the create callback, with plain-language hints: 28 = not installed, 52 = signature/Memory Integrity, …) and the driver's debug log path. Also fixes a real bug both SwDeviceCreate wrappers shared: the 10s WaitForSingleObject result was ignored and the callback HRESULT zero-initialised, so a PnP timeout read as SUCCESS (now E_FAIL init + explicit timeout error). Failure-mode table: design/gamepad-driver-health.md. Linux workspace green; Windows host + drivers CI-compile only, on-box recipe at the bottom of the design doc.

enricobuehler	0f798d62b6	feat(windows-host): pf-vdisplay — fix the ADD/REMOVE wedge + per-client display-config persistence ... Two phases of pf-vdisplay (IddCx virtual display) lifecycle work, both validated on-glass on the RTX box. Phase 1 — fix the long-standing IOCTL_ADD 0x80070490 (ERROR_NOT_FOUND) wedge that ghost-monitor slot-budget exhaustion produced under ADD/REMOVE churn (the reset-script/reboot recurring failure). Validated: 43 reconnect-churn cycles, 0 wedges, monitor-node count flat at 1. * driver: on IddCxMonitorArrival failure, tear the created-but-not-arrived monitor down with WdfObjectDelete + reclaim its id — the asymmetric-with-the-create-failure-path leak that exhausted the 16-monitor MaxMonitorsSupported budget; recover MONITOR_MODES from lock poisoning instead of failing closed (defensive; the driver builds panic=abort). * host: collapse the build-retry churn — hold ONE monitor lease across all build attempts and preempt only on Lingering (not Active), so a cold start does 1 ADD not 8; reap not-present "punktfunk" monitor PDOs on startup (the reset-script step-2 logic, in-process) and self-heal a detected 0x80070490 by reaping + retrying ADD; force-preempt a stuck-Active prior monitor on the begin_idd_setup timeout (the safety net the Lingering-only preempt would otherwise drop). Phase 2 — give each client (keyed by its cert FINGERPRINT) a STABLE virtual-monitor id (1..=15) so Windows reapplies that client's saved per-monitor config (DPI SCALING) across reconnects, and two clients never share/bleed config. Validated: distinct clients -> distinct ids (1, 2); the driver honors the host's id (echoed resolved == preferred). * proto: rename AddRequest._reserved -> preferred_monitor_id (offset 20) and AddReply._reserved -> resolved_monitor_id (offset 12) — byte-compatible (offset asserts), NO PROTOCOL_VERSION bump, so a pre-Phase-2 driver degrades gracefully to auto-id (the host detects it via the resolved echo). * driver: create_monitor honors a host-supplied preferred id via resolve_id (range 1..=15, never collides with a live monitor) and seeds the EDID serial + IddCx ConnectorIndex + ContainerId from it. * host: a persisted LRU fingerprint->id map (%ProgramData%\punktfunk\pf-vdisplay-identity.json), threaded to add_monitor via a set_client_identity no-op trait method (Linux/GameStream unaffected).

enricobuehler	f6490f4c28	fix: complete the docs/→design/ and openapi→api/ rename references ... The file moves (docs/ → design/, docs/api/openapi.json → api/openapi.json) landed in d01a8fd, but the matching reference updates did not — so mgmt.rs's drift-test `include_str!("../../../docs/api/openapi.json")` pointed at a path that no longer exists and the host failed to build. This restores it and updates every reference: - mgmt.rs include_str! → ../../../api/openapi.json (fixes the build) - web/orval.config.ts codegen target, web/Dockerfile, .dockerignore - deb/rpm/Arch packaging install paths - CLAUDE.md, the .gitea CI workflows, code doc-comments, design-doc cross-links docs-site route URLs (/docs/...) untouched.

enricobuehler	00cf51d610	refactor: rename pf-vdisplay-proto -> pf-driver-proto (it spans all drivers) ... The shared host<->driver ABI crate already contains more than the virtual display: the IDD-push frame ring + control plane AND the gamepad shared-memory layouts (XusbShm / PadShm). "pf-vdisplay-proto" was a misnomer — the name now represents all the drivers it serves. Mechanical rename, no behavior change: - git mv crates/pf-vdisplay-proto -> crates/pf-driver-proto (package name + path-deps in the host crate and the driver workspace). - pf_vdisplay_proto -> pf_driver_proto across host + driver Rust, both Cargo.lock files, the workspace members, the CI path triggers (windows-drivers.yml), and the docs/INF comments. The runtime Global\pfvd-* shared-object names are a SEPARATE contract and are deliberately untouched (host<->driver name matching). - The pf-vdisplay DRIVER crate + its INF service name (Root\pf_vdisplay, UmdfService=pf_vdisplay, pf_vdisplay.dll) are unchanged — only the full `pf_vdisplay_proto` token was replaced, never the `pf_vdisplay` driver name. Linux-verified: cargo test -p pf-driver-proto (const size-asserts compile) + cargo clippy -p punktfunk-host -D warnings clean; Cargo.lock regenerated. The driver-workspace side (path-dep + imports + its Cargo.lock) is Windows-CI-gated. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-26 05:38:21 +00:00
